Can't install ChromeOS

[Schefflin]

ChromeOS_image: hatch_stable_r126

https://github.com/sebanc/brunch/releases/download/r126-stable-20240630/brunch_r126_stable_20240630.tar.gz

Run "sudo bash chromeos-install.sh -src image.bin -dst /dev/sda"

Looks like only Brunch installed but chromeos doesn't exist.

I need help
